| Popis: | Za potrebe poređenja skupova podataka osmišljen je pristup poređenjukoji se zasniva na upotrebi grafova. U ovom pristupu razvijene su dvevrste grafovskih predstava: predstave vrednosti koje opisuju skuppodataka i predstave razlika koje opisuju razlike između dvepredstave vrednosti. U ispitivanjima pristupa nad sintetičkim irealnim skupovima podataka, pokazano je da je kroz vizualnoistraživanje predstava razlika i primenu pomoćnih postupaka obrademoguće uočiti korisne obrasce koji prikazuju razlike između predstavavrednosti, a posredno i između skupova podataka opisanih putem ovihpredstava vrednosti. In order to support data set comparison, a graph-based approach tocomparison was devised. In this approach, two types of graph-basedrepresentations were introduced: value representations that represent a dataset and difference representations that represent differences between twovalue representations. The results of approach evaluations on synthetic andreal data sets indicate that, by visually exploring difference representationsand applying auxiliary procedures, it is possible to discover useful patternswhich describe differences between two value representations and,consequently, differences between the data sets corresponding to the valuerepresentations. |
